Abstract
For more than 30 years, the association between the Hawaiian bobtail squid, Euprymna scolopes, and the bioluminescent bacterium Vibrio fischeri has been studied as a model system for understanding the colonization of animal epithelia by symbiotic bacteria. The squid-vibrio light-organ system provides the exquisite resolution only possible with the study of a binary partnership. The impact of this relationship on the partners' biology has been broadly characterized, including their ecology and evolutionary biology as well as the underlying molecular mechanisms of symbiotic dynamics. Much has been learned about the factors that foster initial light-organ colonization, and more recently about the maturation and long-term maintenance of the association. This Review synthesizes the results of recent research on the light-organ association and also describes the development of new horizons for E. scolopes as a model organism that promises to inform biology and biomedicine about the basic nature of host-microorganism interactions.

Abstract
Deep venous thrombosis (DVT) has been previously reported in children with methicillin-resistant Staphylococcus aureus (MRSA). This study reviews our institutional experience by evaluating characteristics and outcomes of children with DVT and staphylococcal infections. Retrospective clinical data from 16 pediatric patients with DVT and staphylococcal infections over a 5-year period was obtained via medical record abstraction. Sixteen patients with a median age at diagnosis of 8 years were included. The most common infection encountered was osteomyelitis (56%). The most common isolated organism was MRSA (63%). Central venous catheters were present in 50% of cases. All patients received anticoagulation with low molecular weight heparin except 1 patient with superficial venous thrombosis who was managed conservatively. Fifty percent of patients had complete resolution of DVT by the end of treatment, 25% of the patients had early disappearance of the thrombus at 7 to 10 days. Only 2 patients (12.5%) had persistent thrombus at 6 months. Staphylococcal infections may increase the risk of DVT in children. Therefore, a high index of suspicion for DVT is warranted in children with Staphylococcal infections (particularly MRSA) to promptly diagnose, treat and minimize complications. Prophylactic anticoagulation in presence of staphylococcal infection, particularly MRSA, may be considered in future studies.

Abstract
Deep vein thrombosis associated with acute osteomyelitis is a rare presentation. Such a presentation can lead to delay in diagnosis especially due to overlapping clinical presentation and usually has a poor prognosis. Only a high level of clinical suspicion can help in diagnosis. We present such case which patient presented with acute abdomen with swelling in lower limb.

Abstract
Background:
There have been an increasing number of pediatric reports of septic pulmonary embolism in the setting of septic thrombophlebitis adjacent to a primary infectious source. Methods:
Retrospective review at an urban hospital. A total of five adults with a documented primary infectious source, adjacent septic thrombophlebitis and septic pulmonary embolism were identified between 2000 and 2011. Results:
The predominant symptoms on presentation were fever and pleuritic chest pain, followed by chills and cough. S. aureus was the pathogen in 4 patients. Only one case had echocardiographic evidence of endocarditis. All patients received IV antibiotics and anticoagulation therapy. No new embolic events or central nervous system complications were noted. Conclusions:
The triad of extrapulmonary infection, contiguous septic thrombophlebitis and septic pulmonary embolism is present in adult as well as pediatric populations. The use of systemic anticoagulation with appropriate antibiotics resulted in clinical and radiologic improvement but no significant complications.

Int J Infect Dis 2012; 16:e236-43.

Abstract
BACKGROUND Clinical manifestations of deep venous thrombosis (DVT) tend to overlap with those of deep-seated musculoskeletal infections (MSIs). Consequently, the incidence of DVT as a complication of MSI may be underestimated. The objective of this study was to evaluate the incidence, clinical features, and outcomes of MSI-related DVT in children. METHODS We systematically reviewed relevant studies retrieved from PubMed and Scopus databases. RESULTS Overall, 93 children with MSIs who developed DVT were identified from 28 retrospective studies. The majority were boys. Osteomyelitis was the most frequent MSI (69/74, 93%). Staphylococcus aureus was the predominant pathogen (83/93, 89%); 61% of these isolates were methicillin-resistant S. aureus (MRSA). Pulmonary involvement, presumably due to septic emboli, was observed in 65% of the included children. Four children died due to multiple organ failure and two due to respiratory distress. In two of the three studies providing comparative data, MRSA infections were observed significantly more frequently in children who developed DVT compared to those who did not. Yet, the respective differences observed for methicillin-susceptible S. aureus (MSSA) infections were non-significant in these three studies. CONCLUSIONS Despite the inclusion of many case reports and the retrospective design of the evaluated studies, our findings suggest that boys seem to be more frequently affected by MSIs complicated by DVT. Moreover, MRSA seems to be more frequently associated with DVT compared to MSSA. Pulmonary involvement appears to be a frequent complication. Prospective studies are needed in order to further clarify this issue.

Abstract
We describe a case of a scapular abscess, osteomyelitis, septic emboli, and occlusive venous thrombosis secondary to community-acquired methicillin-resistant Staphylococcus aureus in an otherwise healthy pediatric patient. This syndrome represents a life-threatening condition that should ideally be recognized and treated in a timely fashion, not only with early antibiotics and hospital admission but also with anticoagulation and possible surgical intervention. Clinicians need to be aware of the severity of the illness that can be caused by community-acquired methicillin-resistant Staphylococcus aureus infections and complications including venous thrombosis and septic emboli.

Abstract
The triad of acute osteomyelitis, deep venous thrombophlebitis, and septic pulmonary embolism is a rare, but life-threatening syndrome in children that requires prompt recognition and treatment. We report two cases of acute osteomyelitis complicated by septic thrombophlebitis and pulmonary emboli. Both patients required operative drainage to remove the septic focus. Recognition of any one component of the triad should prompt a search for the other associated disorders. Aggressive management with early antibiotic administration, anticoagulation, and surgical debridement can be life saving.

Abstract
The development of deep vein thrombosis in an osteoarticular infection in children is rare. We report the case of two siblings with an osteoarticular infection in the hip and in the knee, respectively, who developed deep vein thrombosis and, in one sibling, pulmonary thromboembolism. The only hematological alteration found was reduction of anti-thrombin III in both patients. This reduction was acquired and secondary to sepsis due to Staphylococcus aureus. Anti-thrombin III levels recovered after 2 weeks of treatment. The association of deep vein thrombosis and osteoarticular infection with sepsis should lead to suspicion of hematological deficiencies, including acquired anti-thrombin III deficiency.

Abstract
OBJECTIVE To determine the prevalence and clinical features of deep vein thrombosis (DVT) complicating osteomyelitis during childhood. STUDY DESIGN We retrospectively reviewed medical records of all patients with osteomyelitis admitted to Children's Medical Center Dallas between July 1, 2003 and December 31, 2004. Analysis was performed on patients with proximal upper or lower extremity, pelvic or vertebral osteomyelitis (a subgroup considered to be at highest risk for infection-related thrombosis). RESULTS Thirty-five patients had confirmed osteomyelitis of the proximal humerus, proximal tibia/fibula, femur, pelvis, or vertebrae. Ten of these 35 children (29%) developed DVT during the acute infection based on imaging studies performed. Eight thrombi occurred adjacent to the infection and two occurred in relation to central venous catheters. Six of the 10 children with DVT also had evidence of infection disseminated to lung, brain, or heart, compared with only 1 of 25 patients without DVT (P = .001). Hospitalization was longer in those with DVT than without (33.5 v. 14.2 days, P = .001). CONCLUSION Thromboembolic complications can occur in the setting of osteomyelitis, and affected patients may be at higher risk of disseminated infection.

Abstract
BACKGROUND Venous thrombosis (VT) in children with Staphylococcus aureus osteomyelitis occurs rarely. We describe clinical features of infections and molecular characterization of isolates of children at Texas Children's Hospital with S aureus osteomyelitis and VT. METHODS We reviewed records and imaging studies (chest radiographs, ultrasound, computed tomography, and MRI) of 9 patients at Texas Children's Hospital with acute S aureus osteomyelitis and new onset VT between August 1999 and December 2004. Isolates were fingerprinted by pulsed-field gel electrophoresis and tested for the presence of genes encoding selective virulence factors. RESULTS The mean age of the patients was 10.6 years. All 9 of the patients had osteomyelitis with sites of infection adjacent to the VT. The femoral and popliteal veins were most commonly affected. Two patients had VTs develop on the same side in which a central line had been in place. Four patients had chest radiographs consistent with septic emboli; inferior vena cava filters were placed in 3. Evaluation for hypercoagulable state revealed 3 patients with lupus anticoagulant, 1 with anticardiolipin IgG antibody, and 5 with no defect. Most laboratory abnormalities had resolved at follow-up. Seven patients had infections caused by methicillin-resistant S aureus belonging to the same clonal group (USA300); all were community acquired. Seven isolates carried the Panton-Valentine leukocidin (luk-S-PV and luk-F-PV) genes. CONCLUSIONS The predominant community-acquired, methicillin-resistant S aureus clone in Houston, Texas, (USA300) may have a unique propensity to cause VT in association with osteomyelitis. Management of the venous thrombosis in this setting may be complicated by the rapid evolution of septic emboli.

Abstract
BACKGROUND Primary pneumonia and metastatic pulmonary infection have become more common in patients with invasive community-acquired Staphylococcus aureus disease at Texas Children's Hospital (TCH; Houston). METHODS In this study, we sought to describe pulmonary involvement in children with community-acquired S. aureus invasive infection and to determine whether the presence of genes encoding Panton-Valentine leukocidin (PVL) (luk-S-PV and luk-F-PV) and collagen adhesin (cna) is correlated with pulmonary manifestations. Patients with invasive staphylococcal infections admitted to TCH between 1 August 2001 and 30 June 2004 were studied. Chest imaging and postmortem examination reports were reviewed. Isolates were tested for the presence of genes encoding PVL and collagen adhesin by PCR. RESULTS A total of 47 of 70 patients with community-acquired methicillin-resistant S. aureus (MRSA) infection had abnormal pulmonary imaging findings, compared with 12 of 43 patients with community-acquired methicillin-susceptible S. aureus (MSSA) infection (P < .001). Pneumonia and/or empyema, in addition to septic emboli, were the most common findings. Metastatic pulmonary disease occurred more frequently among patients with osteomyelitis. Severe necrotizing pneumonia was present in 3 children coinfected with influenza and parainfluenza virus. The presence of genes encoding PVL was investigated in 67 MRSA and 36 MSSA isolates. Abnormal chest imaging findings were observed for 51 of 80 patients with PVL-positive isolates, compared with 2 of 23 patients with PVL-negative isolates (P < .001). Only 2 isolates (both of which were MSSA) from patients with abnormal chest radiograph findings carried cna. PVL remained independently associated with abnormal chest imaging findings in patients with secondary pneumonia in a multivariate analysis (P = .03). CONCLUSIONS Pulmonary involvement is commonly observed in patients with invasive community-acquired S. aureus infections. Community-acquired MRSA may cause primary community-acquired pneumonia, as well as metastatic pulmonary disease. The presence of genes encoding PVL is highly associated with pulmonary involvement by S. aureus.

Abstract
BACKGROUND The clinical characteristics and virulence factors related to musculoskeletal infections caused by community-acquired, methicillin-resistant Staphylococcus aureus (MRSA) in children are not well-defined. METHODS In this retrospective study, the demographics, hospital course and outcome of children with musculoskeletal infections were reviewed from medical records and by contacting patients or their physicians. Antimicrobial susceptibilities were determined by disk diffusion. Polymerase chain reaction was performed to detect genes encoding for virulence factors. Mann-Whitney, chi2 and Kaplan-Meier tests were used for statistical analysis. RESULTS Community-acquired MRSA and community-acquired methicillin-susceptible S. aureus (MSSA) caused musculoskeletal infections in 31 and 28 children, respectively. The median numbers of febrile days after start of therapy were 4 and 1 for MRSA and MSSA patients, respectively (P = 0.001). The median numbers of hospital days were 13 and 8 for the MRSA and MSSA groups, respectively (P = 0.014). At follow-up, 2 patients in the MRSA and 1 in the MSSA group had developed chronic osteomyelitis. pvl and fnbB genes were found in 87 and 90% versus 24 and 64% in the MRSA versus MSSA groups, respectively. (P = 0.00001 and 0.017). Ten patients with pvl-positive strains had complications versus no patients with pvl-negative isolates (P = 0.002). CONCLUSIONS Febrile days and hospital days were greater in children with musculoskeletal infection caused by MRSA than in those affected by MSSA, but no significant differences were found in the final outcome. pvl and fnbB genes were more frequent in the MRSA than in the MSSA strains. The presence of the pvl gene may be related to an increased likelihood of complications in children with S. aureus musculoskeletal infections.

Abstract
Deep vein thrombophlebitis (DVT) and septic pulmonary emboli (PE) are rare in children. The association of DVT and acute disseminated staphylococcal disease (DSD) during childhood has not been previously reported. We report 3 children who developed a triad of DVT, septic PE, and acute osteomyelitis with Staphylococcus aureus cultured from blood and bone. One child succumbed, while 2 survived following prolonged, morbid hospitalizations. The rapid clinical deterioration observed in these patients might be caused by the aggressiveness of staphylococcal infection combined with an ongoing showering of septic emboli from the ileo-femoral DVT. We suggest that infected DVT with septic PE had a pivotal role in the development of DSD in these children. The presence of this triad should prompt aggressive treatment with the appropriate antibiotics, anticoagulation, surgical drainage, and assisted ventilation when indicated.

Abstract
Two children are presented in whom thrombosis of the inferior vena cava developed in association with an acute staphylococcal osteomyelitis. One case involved the left femur and the other the left ileum. Both children had diffuse bilateral staphylococcal pneumonia from presumed septic embolization. There were close similarities between their illness and management, except that the child who survived underwent a caval thrombectomy in the acute phase of her illness. It is hypothesized that the thrombectomy played an important role in her recovery.
